SPECIFICATION forming part of Letters Patent No. '286,655 dated April Q, 1905.

Application ined April 19, 1904. Serial No, 203,954.

To (l/Z who/n, it ntf/,y concern.

Be itknown tirati, LoUis Gnosstnnvn, a sub- `iect ot His Imperial Majesty the Emperor of `Russia, residing at Vienna, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in liire- Escapes; and I do hereby declare the following' to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which vi'orm a part of this specification.

The presentinvention relates to iire-eseapcs, and especially to that class oi fire-escapes which are arranged opposite vertical series of windows, and thereby serve as a means ot safety for the inmates in case they are cut ott from the stairways or eX its. The litt of such a ii reescape will customarily in disnse (between operations) be hidden in a pit or hole in the pavement at the bottom and will thereby be protected, on the one hand, against exposure to the weather or wanton injury and, on the other hand, be masked or hidocn. According to well-known li re-escapcs of this type the ropes of the lift are entirely tree, so that they stand exposed to these injurious influences andspoil the appearance of the building.

The invention aims at overcoming these objections by arranging the elevator-ropes w hen not in use in grooves, during which time the whole apparatus in complete readiness is entirely masked and shut in from outside dainage. ln order to make the ropes and other tackle completely inaccessible, the grooves are covered.

The accompanying drawings illustrate such an apparatus, Figure l in trent elevation, Fig. 2 in vertical section, and Fig. 3 in horizontal section, lFigs. 4C and 5 beingl details of the rope-groove shell, Fig. il being a liront elevation, and `Eig. 5 a horizontal section.

@n both sides of a vertical series ol windows are arranged the guideways l, which have, preferably, a U-sliaped cross-section and which are let into the walls of the building' in any well-known manner. The ropes 3 of the litt e are arranged so as to hang close to and lie in the grooves 2 of the guit` eways l, in conscqn ence of which they are com pletcly protected. rlhe lift et is on both sidts provided with two hangers 5 6, each pair of which is connected with a roller device T. Each roller device travels in a guideway l and is carried by one ot' the ropes 3. rflic ropes hns lying' in the grooves are led up over rollers 8 in the root' of the building, where they can be wound on a suitable drum in any well-kno yvn manner to thus etcct coordinate movements of the two ropes. rThe supporting-fran'ies l() of the lift project into the grooves and are there provided with rollers or shoes 9, wliereby the lift will be properly guided. In order te protect the guideways and ropes from being meddled with and from wanton damage, it is necessary to cover the grooves from the ground upto a suitable height. The protecting device shown in Figs. Ll; and 5 is in the 'lorin of spring-actuated hinged doors ll, which carry pivoted catches l, having' inwardly-prejecting lugs 13, between which the rope 3 is extended, which last is provided with buttons la, whose impingement with the catches when the rope is pulled up upon releases said catches.

lVhile the apparatus is out of use the litt is arranged between the guideways in a pit 16 in the ground, which pit may be ordinarily closed by one or more doors l?. lnordcr not to make this hole too deep, it is wel to make the litt capable et folding, as seen in Figs. l and 7When the doors ll are shut, the corresponding doors 17 for the lift will close in the latter when ont of use and protect it against the eti'ectsvot' weather and malicious damage without the readiness ot the apparatus for use .being impaired.

Having thus fully described my invention, what .l claim as new, and desire to secure by Letters Patent, is-

l. rihe combination, with the vertical wall of a building structure, olf a lift, grooved guides for the litt setinto said wall, and littropes connected with the litt and arranged in said guides, substantially as described.
